matlab无线通信的代码认知无线电和频谱感知 认知无线电（CR）是一种可编程的无线电和网络技术（智能收发器），具有自适应性，可以自动检测无线通信信道中的网络流量，并相应地调整其传输和接收，以有效地利用可用带宽。 基于各种输入，CR能够允许用户利用未使用/空闲的通信信道，从而避免无线通信信道中的拥塞。 在本项目中，我们考虑诸如用户数量，信噪比（SNR），总错误率和功率电平阈值（用于频谱感知以近似无线通信信道中的网络流量）之类的参数。 该存储库保存了通用的MATLAB / GNU Octave兼容代码，该代码将上述参数考虑在内，并通过将参数微调为不同的值并执行计算来近似CR的性能。 代码中用于计算的两个主要数学函数是： Marcum Q函数 （上部不完整）伽玛功能 Marcum Q函数 该函数用于通过设置功率阈值来计算用于检测可用频谱的使用的检测概率P d 。 即，Q函数计算概率密度函数P(X ≥ x) 。 因此，我们为参数x配置了一个阈值，并应用Marcum-Q函数来检测大于所应用阈值的信号功率水平X以近似使用信道频谱。 数学方程式如下： （上部不完整）伽玛功能 此函数用于计算错误检测

1. 作者提出了高阶DINA模型：HO-DINA。该模型认为学生得知识点掌握情况受高阶参数得影响，比如学生得学习能力。 2. 论文阐述了如何使用MCMC方法对HO-DINA模型进行参数估计，并基于分数减法数据集进行了测试

Guerci教授的认知雷达入门书籍， Cognitive Radar：The Knowledge-Aided Fully Adaptive Approach

09年新书，很好的知无线电 网络中的频谱接入和管理，下面是IEEE的书评： The book is divided into three parts. Part one is a general introduction to wire- less communication systems, reviewing communication architectures and tech- nologies, as well as resource allocation protocols and dynamic spectrum access, discussing features, research challenges, and standardization. Part two is a further discussion on wireless system design with a focus on analysis of dynamic spectrum access systems. A brief introduction to signal processing and optimization tech- niques is presented, as well as basics of game theory and intelligent algorithms (e.g., machine learning, genetic algo- rithms, and fuzzy logic). Finally, part three discusses in detail dynamic spec- trum access and management. Models and architectures of dynamic spectrum access are introduced and described in detail. The authors first present the cen- tralized dynamic spectrum access model, and later focus on the distributed approach. Distributed dynamic spectrum access is discussed from the algorithmic and protocol perspectives in separate chapters. Finally, a spectrum trading model is presented with its applications to wireless communications. This book is a valuable source of information for people new to the con- cept of dynamic spectrum access. Also, scientists and engineers already involved in dynamic spectrum access research will find this book a good reference source. This is one of the few books on the mar- ket related to dynamic spectrum access and cognitive radio written completely by the authors themselves. Therefore, it is very cohesive, has a very good flow, and does not repeat itself while intro- ducing new concepts, as do many edited books on a similar topic available on the market. Many concepts of dynamic spec- trum access are well systematized in the book, and the literature review is very broad and complete. One small draw- back is a bit too lengthy introduction to wireless communication systems in part two of the book (which can e
